Oh how I wish that you were my math teacher when I was little. All I learned was that I’m a math idiot. When I watch this I, for the first time in my life, don’t feel anxiety when it comes to math, but somewhat curiosity and a little butterfly of joy fluttering in my heart. It’s a bit late for me to learn math (I’m 57)...but it is a joy to feel what I mentioned early in my comment, so THANK YOU! All the best from this Swedish old gal!🙂
I said the same exact thing watching him lol, he would have made math alot easier for me in school back then, if he had been my math teacher, because he explains everything very well and so perfectly.
@@coilsmoke2286 I think he's references the formula at the end of the video for the day of the week. I tried it on my birthday too and got 361.392857143. I don't understand how that formula is supposed to work, if the year you were born isn't divisible by 4 you will never get a whole number.
I’m so glad i watched this. My parents had ‘teacher’s conferences’ cuz I couldn’t memorize my times tables in third grade. Truth is I couldn’t do it. I figured out I could calculate the answers and if I stopped having fear about what I couldn’t remember I could just give sequential answers and my teachers thought I’d been reformed or something. It was very traumatic for me at the time; over 40 years later and the memory of this circumstance is still vivid and disconcerting. Now I see the logic wasn’t flawed
I hated math and science all through school due to how these were taught. And considered myself inept at both as a result of the poor grades I got and the constant negativity about it by teachers and parents. Yet as a kid I was fascinated with science and all hours of the day I was more or less doing calculations -- had an innate, acute understanding of math as well as science, which is basically mathematics -- but all those years I didn't know it ... didn't realize my own competencies in these matters (bad pun) until I was about 25 years old. At age 28 I entered college and took sciences and math and earned a 4.0 doing math my way. I'm not a calculator like this guy but I have the same healthy relationship with math.
This guy has won multiple awards, is booked for his talents, calculates faster than the student can enter digits. Yet tge majority of people in the comments are complaining and trying to discredit half of what he says. This is why only 1% of people have over 90% of the world's wealth. Noone is willing to take advice from people who can actually do it.
2 years later your words still hold true. All people wanna see is the people at the top fall down and someone take their place and for the cycle to continue. No one wants to learn and improve, because criticizing is easier and faster.
Im sure that last part has nothing to do with inherited generational wealth, multinational monopolies, insider trading by the political class, an economic system that by nesecity devalues the work of the 90% of workers, etc. 🙃

31:07 If you use this method, you might still have to carry 1. If you have, for example, 47×11=517 The first digit in the one's place (the 7) will always fall but the digit in the hundred's place will always carry 1 when the two digits add up to more then 9. (Btw the middle digit is the 10's place) I just had to point that out. He's still a genius... Remember, If you walk through your familiar memories enough, you will find that you can create new paths (new memories) best by adding them to old structures (old memories). Always have more then one route to your destination. 🤔
Gem in Eye of Taurus Yeah the carry 1 was missing. But I found some methods to get the right answer. So I am using this new guide to think of new ways, which I find arithmetic in math enjoyable.
So basically you trained to feel repetitive patterns of mutation of a value. And finding higher patterns of small compound patterns of number differences. And learned to do it so fast you can instantly feel the number, that's amazing. And the moment where you revealed the truth about our education system I dropped a tear, so true... My parents almost sold everything I have because I didn't get how other kids were able to memorize so much information and be able to work with it without having to think it through, I didn't have that muscle memory ability
You can skip the first 28:00 minutes of it so you can learn how to add 2 digit numbers faster, and then at 31:40 he teaches the fastest way to multiply by 11... that's it!
The adding works for numbers of all sizes, just work your way from left to right. I've been doing it like this for most of my life I was hoping he'd have a good trick for multiply-ing big numbers. Didn't know about the 11 trick (which stops working after 90), but that doesn't work for any other numbers.
I don’t know why all the comments are so negative. I enjoyed this a lot, learned a few things, and it got me to start thinking of math and education differently. Plus this guy has lived a full life with tons of lessons to teach. Props to him for all he’s been through !
This isn't really relearning math, it's relearning arithmetic. Some useful techniques here, but I don't think this is the way to change peoples perception of math. This just further emphasizes the misconception that the purpose of math is to become human calculator, which is frankly a sill goal when we all have computers in our pockets. Teaching the beautiful, elegant, and creative fields of math is the real way to get people to fall in love with the subject. Right now our K-12 mathematics focus is essentially restricted to topics developed by the early 1700s, ignoring the subsequent 300 years of progress. This would be like ignoring literature more modern than Voltaire. No wonder people find math dry! Modern subjects (abstract algebra, graph theory, mathematical logic, etc.) could easily be incorporated, and they are generally so much more inspiring than slogging through some dull trig-identity problem (or learning how to rapidly multiply 3 digit numbers, for that matter).
@Lanz Friszt The Basel problem has such a wonderfully unintuitive (at least to me) solution, which makes seeing the proof all the more revelatory. Great RUclips suggestion, 3blue1brown is a wonderful channel for anyone wanting to get a sense of what math is really like. The book "Love and Math" is another great option for those outside the field interested in gaining insight into the beauty and elegace left out of their math education.
Yeah but the point is that most kids don't get anywhere near actual math because their first 11 years of education are around arithmetic which is taught really badly. If you make the arithmetic fun (and allow kids to figure out patterns in numbers... that sound familiar?) it gives them a better opportunity in actual math.
@@piotrk3897 I am better at Math than you then. xD Blissful ignorance, you have to suffer, before you can get better. You are a first world problem child because you don't have the patience for a free video that landed on your feed.
@@HaloWolf102 whoah there man! That was probably a joke. But I kinda agree with you... what if you play a piano piece, make one mistake, and all the audience walks out of the room? That unfortunately happened to me, and my heart was broken. I don't say making mistakes is good, but such ignorance...
Well I for one am greatly appreciative of him doing this. I wish I could thank him in person. If I never see you dude, just know this really can and is helping people
one of the greatest downfalls of my life is the fact that expecially when it comes to math I have failed miserably all the way into my adult years and as I sit here now and it happened to me exactly like he said I was asked to the board got the question wrong and was completely humiliated and since that day Iran and cowered away from marh right up until this day and I want to say thank you to him for the knowledge he has shared because today was the first day I solved a math equation not for memory but through my own process that I learn from him in less than 5 minutes I've showed this to my eleven-year-old son and we both are better for this video is giving me the strength to strive for more thank you sir
A 42 minute and 33 second video that keeps me watching the whole time. And then I get to the end and find out there's another part… And I want to watch that, too. And it's all about math.
@@divyoroy9056 Thanks, doesn't sound like a rapper I want to listen to, but that's superficial and judgemental on my part so do you have a tip for me which song of his to listen to? I don't know a lot of rappers that have great bars on math. Haha. I root for Nas or Eminem being the greatest of all time, sticking to the subject on rap/hip-hip, my favorite kind of music.
I think him "showing off" is an integral part of why most of you made it to the end. How are you to be impressed or even remotely interested in what he had to say if he did this ANY other way? He was incredible, in my opinion.
I was exposed to learning math when teachers used corporal punishment in the classroom for any type of behavior they did not like. Therefore, I was afraid of learning math and being whipped down. I got whipped anyway because I could not learn or did not have a bit of confidence to learn under those conditions. I have not been able to overcome this trauma and never went passed fractions. I share my sad story because today's learners have all the technology and teaching methodology to learn (without getting hit on the head with a ruler if you couldn't remember some math concept).
*hugs* Thanks for sharing your story and it's so unfortunate you went through that terrible school experience. My boyfriend is 20 years older than me and part of him still thinks it was ok or good that physical abuse was enacted by teachers and parents.. *sigh* So, at least you know that it was wrong and not your fault.. I want to recommend the best, most effective and easiest healing modality for you to try, if you will. It is called EFT (Emotional Freedom Technique) tapping therapy, and you can find lots of videos for help with it here on youtube. Just search EFT tapping, or EFT + an issue you want to address. It is so simple, though you may feel a little silly doing it. The results it gives are mindblowing for many people. It has been clinically researched and there's so much to say about it.. I'd go on but don't want to deter this being read for being even longer than I've already made it.. however I'm around if anyone wants to know more. But please look it up and try it for a few minutes, hopefully you will see quickly how much it's bound to bless you 💗
I am so genuinely angry at the school system. I used to do math like this, but due to them always forcing us to show work they would criticize how I calculated things. They trained us all terribly to the point where it takes me forever to do simple math because I forgot the easy way I once knew.
Yep, similar thing happened to me. Worse even, because I was a year ahead in math, but my algebra teacher had awful breath all the time, so I refused to ask for help. My grandparents requested I be moved to another class, and they got their wish! I was put in a remmedial math class and was a year behind everyone else for the rest of joniour and senior high school.
@@ruthlessadmin That's awful! Teachers are expected to have good hygiene, I wish the school would've just given her a dental care gift basket instead of moving you.
I would do long complex math in my head. my teachers just accused me of cheating and failed me. most people have very weak visual minds and cant just hold an image and manipulate it. Most don't have any visual mind at all. If you were to tell that same teacher to picture the house they grew up in walk out the front door and down the street they would struggle to describe the environment. The visual mind can be seen as the spiritual third eye. Some peoples just don't work.
@@m1galler I was too young to be able to do anything complex, but I did the same with math equations in my grade levels. I understand what you mean about the visualisation. I'm very fortunate as a writer to have a very vivid imagination, almost as if I'm there in certain situations. I can't imagine not having that skill considering how much I adore reading. When I read I don't see the words, I get lost and see just the environment and scenes happening. It's wonderful.
Nope. I continually get videos recommended that I have watched (they show the red line underneath them that acknowledge that) but there they are, time after time. Also as A9_s0ccer_kid says they just throw a whole lot more of the same - vaguely the same - type of video at you.
Thank you Scott. It takes much courage to expose your gift with numbers to the world. My suggestion to you is to clarify that many of your tricks only work in an English speaking world. According to google there are "6,500 spoken languages in the world today.
We also use different number systems. Like in Korea we're taught both Western style ("Arabic") numbers and Chinese numerals, and they both use two very different number.
@@constitution_8939 Not for nothing, but The Hindu-Arabic Numeral System was actually invented in India around 700 AD, roughly 100 years after Muhammad founded Islam. It was adopted by the Third Caliphate another 100 years after that, and subsequently by Europeans another 150 years or so after that. It was one of maybe six smart things we did while we were flailing in the depths of our thousand years or so years of abject and deliberate ignorance.
@@RelapseTech "It was only about thirty years later, after I traveled the world that I think I cam upon the answer." He identified the problem as a child. I personally think that's a story he tells to provide context for what amounts to a tool that might be handy for some teachers and students learning about counting and simple arithmetic. Once you get to ... jesus... algebra, even... it doesn't really matter what the numbers look like anymore. You know what they represent. After that, getting fast at arithmetic is just a matter of practice. I'd rather practice something more involved, personally. But to each their own, I guess.
And to think, I only popped down here to find this exact comment and thank the person who made it. Imagine my surprise when every other reply was pure ignorance.
for those that dont want to hear roughly 20 min of his life and/or doesnt care about his thinking and only here for the math stuff use these timestamps: start here-> 16:59 when u reach~32:56 skip to this-> 39:27
Pity that the person who presented it didn't do the same edits on the day. This guy has got to be the most long winded and boring pseudo-smart person that I have ever heard. I also don't really like the cheap carnival tricks either.
@@somedood8923 , when you do a fast technique of maths which only work with limited numbers. Example: a trick to solving 9 timetables. 9 x 8= 72 The trick is to take 1 from 8. Which equals 7. Than take 7 away from 9. Which equals 2. Now put 7 and 2 next to each other. The answer 72. But try doing the same thing with 9 x 10 = or 9 x 11 = or 9 x 12 = or higher. It gets too complicated.
Well I still can't do math... BUT I sincerely enjoyed this man's story. It's amazing how EVERYONE HAS AN INSPIRING STORY if you're willing to listen and hear what they have overcome to get this far. Gotta Luv That!
Yeah lol I saw that but still impressive that he can calculate that. I guess somehow his brain can work reallly fast to identify patterns. For example 98 is 14 *7
the method you all salty commentators were taught at school is taught this way because it is ONE method that works for every situation. No, it is not the fastest one, nor the most efficient, but it works. Flawlessly. What he's showing is nice, but it's basically memorizing multiple methods instead of memorizing multiplication tables and one method.
I actually remember doing it sumular to how he does it. Left to right. And i remember it was a great little boost when i found i coukd do the problems faster than most kids. Until the teacher said I couldnt do it that way and marked the answers wrong if indidnt show my work. I basically quit school not long after that. Im 35 now lol that was 25 years ago
@Vano Scrap: I have to disagree. But just on the part that the method taught at school is slower and less efficient than the method he showed. No matter if you are going from first to last digit or the other way around, you are doing the same calculations and thus the same amount of calculations, so it's equally fast. But when going from left to right, you have to keep the result in mind, since it can change, if the next digit exceeds 10. On the other hand, you can write the result down when going from right to left, since it won't change anymore. That may be of no importance, if you are adding four double digit numbers, like he did, since anyone can keept those in mind. Try his method on 25 10-digit numbers and you will fail miserably, since you have to remember way too much stuff and there is a high change you get lost on your way. That won't happen with the method you learn in school, since you can always write down your results. So no, the method taught in school isn't slower or less efficient. It actually is equally fast/efficient on easy calculations and way faster and more efficient on difficult calculations. It's just that we read from left to right and thus are trained to think that way and therefor some people struggle with doing math the other way around. But especially for those who struggle with math it's even more important to have one method that fits all and lets you write down interim results instead of forcing you to keep them in mind and add to them midway. His multiplication with eleven is even worse. Having a different method for just one multiplier makes it more difficult. Having one method that fits all is easier to learn. I'd get such a shortcut, if it were about a multiplier that is more difficult to calculate (like 5, where I just add a 0 behind the last digit and cut in half, because it's actually easier than multiplaying every digit with 5), but eleven is the easiest multiplier after 0, 1, 2 and any multiple of 10. You just add a 0 and add the number itself. Mathematical wise it's actually the same thing he does. So all in all his methods are just gimmicks that work in a limited amount of cases, which isn't really useful and just adds to the confusion of those who already struggle with math.
Great story of your life from Graduation, USAF, homeless, favorite part is you going to kids classes and spending that birthday moment. After all I am a big kid at heart and enjoy watching them learn and grow, mentally and physically.
"They" weren't fighting Roman numerals at all. The people who devised the numerals we use were Arabs, adapting them from India scripts, from whom they also adopted the concept of zero (unknown in the Roman world). Look at the scripts of India and of the Semitic world (Aramaic and the beginnings of writing Arabic in Kufa). Do you see the angular shapes being suggested here? No, you don't. You see curling shapes. Can you easily make those angular shapes with the writing implements of the places and times? No, you cant, you'll bust the nib you've crafted if you try changing direction precipitately like that. You can draw straight lines, but you change direction in a curve, not at an angle. The Romans didn't invent everything, you know, and they, for daily purposes, most wrote on soft clay slabs with a small pointed stick, a system in which sharp angles were feasible.
I have done a lot of calligraphy and I can tell you that making angular lines without breaking nibs is the Norm! I have used steel nibs and bamboo nibs, quills, all work just fine, you have to lift the pen at times, just like we do in cursive writing the English language..
The reason algebra is associated with arabs is because of Al-Khwārizmī a 9th-century Persian mathematician, ha was a zoroastrian who was forced to convert (or die) by muslim rulers because Persia had been conquered by the Islamic armies. He translated, formalized and commented on ancient Indian and Greek works.
You're thinking of Linear B. The romans did use clay tablets but for most things they had actual paper scrolls. See here: www.extremetech.com/extreme/225338-roman-scrolls-long-buried-by-vesuvius-reveal-their-secrets
@Smudgy nah I can't hear them that good either and I'm using the Bose quietcomfort 35. They're pretty good. But I have to agree with you, he could've admit his "mistake".
I thought this guy was great, idk why everyone dislikes him. Who cares if he shows off a bit. I do wish he showed the multiplication stuff he was talking about though.
U could try vedic maths for that.. its again given by India as zero is... you will find videos on you tube.. else you can contact me... i will share tricks with you...😊
Rachel Harper When someone can do something that others can’t. Those others instantly start making justifications for why it’s no big deal and how everyone can do it but they just don’t feel like it because it’s not important. It’s a study in self delusion and the classic “hater” complex where people have to try to take everything down in order to maintain their own fragile egos
I was taught to do this sort of thing in class where we were not allowed to use any calculating device at all. No pencil, paper, slate or chalk. (The calculator was still 40 years of near science fiction away) you were required to clear your desk, and the Teacher would speak the math problem, (again, no writing of any kind) Our Teacher had 28 of us in class, and he would start with two-digit numbers, addition then multiplication of the same two numbers. The entire class could go thru 56 problems *without error* in just over one minute. Now imagine doing this six days a week, for one hour and a quarter, every morning. I'm not bragging. The point here is that doing the math entirely in your own mind allows you to think about numbers and basic functions in a way that is most comfortable for the individual. The teaching of math is hung up on teaching techniques that are outmoded, and dependant on rote memorization for learning, but never for application.to thinking processes. These techniques "break the box" that most people get their minds shoved into by force when it comes to learning math as a functional application. These techniques should be taught in every school along with Vedic math. but the people who resist these changes the most will shock you- Textbook publishers who have made millions selling the same teaching methods every year between new covers. Teach this method to kids, and they pick it up like magnets. Once you free their minds and show them they can *enjoy* learning, nothing in the world but old ideas ever hold them back again. Imagine what a world that might be in 20 years time.
What useless shit to waste brain space on. I'm doing a masters in physics and have a bachelor in physics and mathematics and I can tell you that there is almost a negative correlation between how good people are in those fields and how good they are at multiplying and adding numbers in their head. Knowing tables are a complete waste of headspace. It is not going to make life easier for anyone in this modern world and it is pretty much non-constructive for learning real mathematics.
@@pawthorne7089 Not just alive, apparently, but old enough to be studying difficult enough maths that a calculator might be used for it today (in UK education that would probably mean 11+. but Roci may well be from somewhere else in the world).
An old man showed me a different way to do division. He thought the teacher would be impressed. She told him I was" just confusing the child" .They must learn to do it as the department of education requires and it was also required to write everything on paper as otherwise I was just guessing at the answers. Memorize everything, write it on paper , prove that you did it their way and no oral testing or doing it in your head. That was 1st grade, by 3rd grade they tried to teach us algebra as an experiment and it was a failure. Real and non real numbers? To a 8year old?non real is imaginary and could not be written down on paper. Who was Confusing? Algebra came in the 8th grade and nearly noone could do it. Thanks to the Department of Education ,State of New York 1960-70's They were stupid.

This guy is the human calculator but man is he taking his time explaining this
We've got someone in my village who does Arithmetical operations, be it plus, minus, multiplication or division instantly. Most surprisingly, the person was a drop our in secondary school. More so, he tells number of days, hour, minutes and seconds given any date and does it precisely. He tells dates when number of days from a particular date is given to him. The man was tagged human computer. He lived in a town Zaria in northern Nigeria. The man lived in the early 90s and I do not know where he is at the moment.
I learnt to calculate in certain ways. I learnt to calculate in more ways with years and experience. Some things are taught with time, effort, luck or if "you have it in you"; at school they teach us mostly the basics, things that have a solid base. It's up to the teachers to show us how to think smarter and quicker, but even then not everyone likes the same things.
Everyone saying he is showing off I guarantee are the same people who take pics on social medial of every new thing they get. This dude found his own way to learn to me that’s worth showing off.
I like how the whole angles-in-numbers thing was some irrelevant, ad-hoc sophistry that didn't even work right and had to actually alter some of the numbers drastically.
That's not accurate. Numbers are not written the same today as in the past. In the past you could count the angles to know what it represented, as he showed.
When he's going on about where the symbols for those numbers came from, this is fairly well known knowledge, not sure why it took him 30 years to find it. Additionally, half the stuff he's saying only works in ENglish and it pure happenstance. The rest is just mnemonic devices that will work for some but not for others.
My father did this lightening fast. I find now that I already have the answer in my head, but make myself go through what we did in school. Thanks school system!
Janus is the Roman god of beginnings, transitions, time. Since Julius Caesar made the Julian calendar he thought it would be appropriate to make the first day of the new year on the first day of the month of Janus (January). The original 1st day of the the new year was April 1st. When new years day was changed to January, people would still say happy new year on April first, and people would call them April fools for forgetting it was changed to January.
the math have never interested me. I was happy to have understood the basics of algebra. But strangely, I was the best in geometry and I was able to memorize the calculation tables entirely (without really to understanding them). In the early 80's when the first computers like the SINCLAIR ZX 81, COMMODORE C-64 and AMSTRAD were available, I started learning BASIC and MS-DOS - but only because I was able to memorize everything the programming schemes and conclude the logical sequence. So I became a cartographer for the mapping of sattelite images in the military. But even today I do not understand maths in context - but only if I associate these equations with an image or an object in the form of variables ... I believe the brain of each one of us works differently but we get everything (more at least) to the same result ;-)
29:00 I wonder if anyone adds like me: I add from right to left, but I look in the right column for numbers that add up to 10, by scanning. So in 1st example he used, 7, 2, 1 instantly popped up in my head as a 10, so I don't add those, I add the remainder to it, then add the total with the total on the next column, which same rule can be applied. If you have for example 2, 2, 2, 2, 2 or 6, 2, 2 , that's an instant 100, I don't add them but whatever is left in the column gets added to it. Also works by scanning which rows can be combined to make multiple of 5, and you count how many times the pattern appeared, then you add whatever rows couldn't fit to the pattern. I'm nowhere near capability of this guy, but I can add in my head faster than a "normal" person. 2nd case - was very slowly delivered, 6, 3, 1 instantly recognized as a 10, added 8, then added digits in 2nd column - 70 plus 18. In a nutshell, is recognizing the patterns of numbers that create a fixed amount (usually 10) and add how many times that pattern repeats itself. Hope this is not very confusing, I'm really curious if anyone else uses this method.
I think this Method of adding from left to right works in the English language but at least in Germany to say like 54 we say vier=4 und fünfzig=50 so its easier to add up the right diget first
I cannot sufficiently dislike this video with just one thumb down, RUclips. I need to actually block the entire channel from ever appearing in my feed again.
I Like Flansburg, and I have Improved my math skills by learning his techniques. But I disagree with thinking of the first finger as 0. Sure we should count from 0, I don't dispute that, but we should start with no fingers up as 0, not the first finger. We should make sure that 0 is not being translated as 1, but as the point before you start counting, or adding in anything.
Think of an infinite line and what breaks it up into units that we can use, e.g. to measure the distance from your house to my house or from my planet to your house. We have to pick a more-or-less arbitrary starting point, which we call zero, and we have to define a unit of length, say a meter, and lay it out on that line with one end at zero. Then the end of the first meter is 1. In between are fractional values of that first number, which we need to be able to deal with. So in one way it is very natural to start with zero. What we were doing with 0-9 and with 1-10 was not made clear to me in elementary school, and I still get confused and have to draw a picture or two to get myself clear on things. It would have been more natural if in school we would have started with measuring distances, specifying that we start having gone zero miles, then when we have gone a mile we put down a roadside marker saying, "One mile form home," and so forth. We could do the same thing, filling a measuring pitcher up with a third of a cup of water, adding more water to make a half cup of water, and so on. Starting with one little lamb, two little lambs seems natural, and indeed that is probably the way numbers were first used. If you were a sheep herder you hoped you had only whole lambs at the end of the day, and you didn't count a zeroeth lamb returning to the fold, but on the whole, starting out this way can lay down landmines for the future.
The day-calculation trick that he mentioned looks like ["Sun","Mon","Tue","Wed","Thu","Fri","Sat"][((Y+(Y/4|0)+D+[0,3,3,4,1,4,6,2,5,0,3,5][M-1])/7|0)%7] in JavaScript. Which is kind of interesting because every web browser understands JavaScript even if it isn't connected to the web... just create a New Tab, press F12, click Console, then input a date like Y=2001; M=9; D=11; Press Enter, and paste in the algorithm, and press Enter again, and it'll tell you the day of the week, which in this case is Tuesday. It's not quite correct, though, because it doesn't work correctly before 1900 or after 2100 because those years are normal years, not leap years.
Great guy. Great teacher. He’s so right. As a kid I wanted the reasons for the way things were. They needed that .....fir things to be meaningful. Less bogus. I did not know the angles thing and I asked the same question as a kid. This is an amazing video.
He is very skilled, but is not being fully forthcoming in how he achieves some of his results and is not as informed as he pretends to be. The cube root trick he does early in the show is a memorization trick, not a calculation and can be learned by anyone with a decent memory in half an hour. The limitations are that the cube root must be a 2 digit integer and the number he is given from which to "calculate" the results must be a perfect cube. You can find a youtube video showing how to perform this trick if you are interested--I think tecmath has one. You will need to memorize the cubes of the numbers from 1 to 9 and that plus a very simple 2 step method is all you need. No calculation at all. In addition, the story about how the numbers got their shapes is apocryphal. The original shapes looked absolutely nothing like the shapes he drew.
I realised he must be memorising the cubes, as he didn't even listen to the whole number before answering so couldn't be performing a calculation on it.
@@discoepfeand yea noticed that too, same with anything for his last step that goes > 10; 19*11, 28*11, 37*11, 46*11, 55*11, 64*11, 73*11, 82*11, 91*11; or... 29*11, 38*11, 39*11, 47*11, 48*11, 49*11, etc...
3 goes in the hundreds column and 7 goes in the ones column, giving you 3_7: since 3+7 gives a two-digit answer, regular addition applies to the hundreds column and thereby increases by one hundredth or 4 placed in the hundredths column. That zero tens and four hundreds. Hence, the answer is 407 (instead of being stuck with 3+10+7 or erroneously arriving at an impasse of 3107). Get it? Got it? Good! 👌💪🏽✅🤓✌️
Dan your opinion is just that. arithmetic is part of math and all math is algebra. It depends on what country you are from on how you define word for math. You people from your country even spell it funny.
Oh how I wish that you were my math teacher when I was little. All I learned was that I’m a math idiot. When I watch this I, for the first time in my life, don’t feel anxiety when it comes to math, but somewhat curiosity and a little butterfly of joy fluttering in my heart. It’s a bit late for me to learn math (I’m 57)...but it is a joy to feel what I mentioned early in my comment, so THANK YOU! All the best from this Swedish old gal!🙂
It’s never to late to learn something new.

I’m so glad i watched this. My parents had ‘teacher’s conferences’ cuz I couldn’t memorize my times tables in third grade.
Truth is I couldn’t do it.
I figured out I could calculate the answers and if I stopped having fear about what I couldn’t remember I could just give sequential answers and my teachers thought I’d been reformed or something.
It was very traumatic for me at the time; over 40 years later and the memory of this circumstance is still vivid and disconcerting.
Now I see the logic wasn’t flawed
I hated math and science all through school due to how these were taught. And considered myself inept at both as a result of the poor grades I got and the constant negativity about it by teachers and parents. Yet as a kid I was fascinated with science and all hours of the day I was more or less doing calculations -- had an innate, acute understanding of math as well as science, which is basically mathematics -- but all those years I didn't know it ... didn't realize my own competencies in these matters (bad pun) until I was about 25 years old. At age 28 I entered college and took sciences and math and earned a 4.0 doing math my way. I'm not a calculator like this guy but I have the same healthy relationship with math.

If you use this method, you might still have to carry 1.
If you have, for example,
47×11=517
The first digit in the one's place (the 7) will always fall but the digit in the hundred's place will always carry 1 when the two digits add up to more then 9.
(Btw the middle digit is the 10's place)
I just had to point that out. He's still a genius...
Remember,
If you walk through your familiar memories enough, you will find that you can create new paths (new memories) best by adding them to old structures (old memories).

So basically you trained to feel repetitive patterns of mutation of a value. And finding higher patterns of small compound patterns of number differences.

This isn't really relearning math, it's relearning arithmetic. Some useful techniques here, but I don't think this is the way to change peoples perception of math. This just further emphasizes the misconception that the purpose of math is to become human calculator, which is frankly a sill goal when we all have computers in our pockets. Teaching the beautiful, elegant, and creative fields of math is the real way to get people to fall in love with the subject.
Right now our K-12 mathematics focus is essentially restricted to topics developed by the early 1700s, ignoring the subsequent 300 years of progress. This would be like ignoring literature more modern than Voltaire. No wonder people find math dry! Modern subjects (abstract algebra, graph theory, mathematical logic, etc.) could easily be incorporated, and they are generally so much more inspiring than slogging through some dull trig-identity problem (or learning how to rapidly multiply 3 digit numbers, for that matter).

Yeah but the point is that most kids don't get anywhere near actual math because their first 11 years of education are around arithmetic which is taught really badly. If you make the arithmetic fun (and allow kids to figure out patterns in numbers... that sound familiar?) it gives them a better opportunity in actual math.

This is what humanity is all about.. Hard times but finds something that our own mind can do easily.
I was exposed to learning math when teachers used corporal punishment in the classroom for any type of behavior they did not like. Therefore, I was afraid of learning math and being whipped down. I got whipped anyway because I could not learn or did not have a bit of confidence to learn under those conditions. I have not been able to overcome this trauma and never went passed fractions. I share my sad story because today's learners have all the technology and teaching methodology to learn (without getting hit on the head with a ruler if you couldn't remember some math concept).
*hugs* Thanks for sharing your story and it's so unfortunate you went through that terrible school experience.

Which equals 2.
Now put 7 and 2 next to each other. The answer 72.

Well I still can't do math... BUT I sincerely enjoyed this man's story. It's amazing how EVERYONE HAS AN INSPIRING STORY if you're willing to listen and hear what they have overcome to get this far. Gotta Luv That!
Its probably as fake as how he "came up" with his tricks that lots of people know and already exist since forever.
I remember when he graduated from UofA. I started my Memory Programs that year. He also began selling a program IIRC teaching easier math
5:26 the fact that the audience is impressed by memorizing the decimal pattern of 2/7 shows how little they know about numbers
Yeah lol I saw that but still impressive that he can calculate that. I guess somehow his brain can work reallly fast to identify patterns. For example 98 is 14 *7
the method you all salty commentators were taught at school is taught this way because it is ONE method that works for every situation. No, it is not the fastest one, nor the most efficient, but it works. Flawlessly.
What he's showing is nice, but it's basically memorizing multiple methods instead of memorizing multiplication tables and one method.
I actually remember doing it sumular to how he does it. Left to right. And i remember it was a great little boost when i found i coukd do the problems faster than most kids. Until the teacher said I couldnt do it that way and marked the answers wrong if indidnt show my work. I basically quit school not long after that. Im 35 now lol that was 25 years ago
Doing math left to right instead of right to left is flawless too.
Well someone here is salty...
This method is not faster anyway.
@Vano Scrap:
I have to disagree. But just on the part that the method taught at school is slower and less efficient than the method he showed. No matter if you are going from first to last digit or the other way around, you are doing the same calculations and thus the same amount of calculations, so it's equally fast. But when going from left to right, you have to keep the result in mind, since it can change, if the next digit exceeds 10. On the other hand, you can write the result down when going from right to left, since it won't change anymore. That may be of no importance, if you are adding four double digit numbers, like he did, since anyone can keept those in mind. Try his method on 25 10-digit numbers and you will fail miserably, since you have to remember way too much stuff and there is a high change you get lost on your way. That won't happen with the method you learn in school, since you can always write down your results.
So no, the method taught in school isn't slower or less efficient. It actually is equally fast/efficient on easy calculations and way faster and more efficient on difficult calculations. It's just that we read from left to right and thus are trained to think that way and therefor some people struggle with doing math the other way around. But especially for those who struggle with math it's even more important to have one method that fits all and lets you write down interim results instead of forcing you to keep them in mind and add to them midway.
His multiplication with eleven is even worse. Having a different method for just one multiplier makes it more difficult. Having one method that fits all is easier to learn. I'd get such a shortcut, if it were about a multiplier that is more difficult to calculate (like 5, where I just add a 0 behind the last digit and cut in half, because it's actually easier than multiplaying every digit with 5), but eleven is the easiest multiplier after 0, 1, 2 and any multiple of 10. You just add a 0 and add the number itself. Mathematical wise it's actually the same thing he does.
So all in all his methods are just gimmicks that work in a limited amount of cases, which isn't really useful and just adds to the confusion of those who already struggle with math.
I havent been excited like a kid about math since I first started programming. I wish you were my teacher
Great story of your life from Graduation, USAF, homeless, favorite part is you going to kids classes and spending that birthday moment. After all I am a big kid at heart and enjoy watching them learn and grow, mentally and physically.
"They" weren't fighting Roman numerals at all. The people who devised the numerals we use were Arabs, adapting them from India scripts, from whom they also adopted the concept of zero (unknown in the Roman world). Look at the scripts of India and of the Semitic world (Aramaic and the beginnings of writing Arabic in Kufa). Do you see the angular shapes being suggested here? No, you don't. You see curling shapes. Can you easily make those angular shapes with the writing implements of the places and times? No, you cant, you'll bust the nib you've crafted if you try changing direction precipitately like that. You can draw straight lines, but you change direction in a curve, not at an angle. The Romans didn't invent everything, you know, and they, for daily purposes, most wrote on soft clay slabs with a small pointed stick, a system in which sharp angles were feasible.
I have done a lot of calligraphy and I can tell you that making angular lines without breaking nibs is the Norm! I have used steel nibs and bamboo nibs, quills, all work just fine, you have to lift the pen at times, just like we do in cursive writing the English language..
You can't see the wood for the trees.
The reason algebra is associated with arabs is because of Al-Khwārizmī a 9th-century Persian mathematician, ha was a zoroastrian who was forced to convert (or die) by muslim rulers because Persia had been conquered by the Islamic armies. He translated, formalized and commented on ancient Indian and Greek works.

When someone can do something that others can’t. Those others instantly start making justifications for why it’s no big deal and how everyone can do it but they just don’t feel like it because it’s not important. It’s a study in self delusion and the classic “hater” complex where people have to try to take everything down in order to maintain their own fragile egos

I was taught to do this sort of thing in class where we were not allowed to use any calculating device at all. No pencil, paper, slate or chalk. (The calculator was still 40 years of near science fiction away) you were required to clear your desk, and the Teacher would speak the math problem, (again, no writing of any kind) Our Teacher had 28 of us in class, and he would start with two-digit numbers, addition then multiplication of the same two numbers. The entire class could go thru 56 problems *without error* in just over one minute. Now imagine doing this six days a week, for one hour and a quarter, every morning. I'm not bragging. The point here is that doing the math entirely in your own mind allows you to think about numbers and basic functions in a way that is most comfortable for the individual. The teaching of math is hung up on teaching techniques that are outmoded, and dependant on rote memorization for learning, but never for application.to thinking processes. These techniques "break the box" that most people get their minds shoved into by force when it comes to learning math as a functional application. These techniques should be taught in every school along with Vedic math. but the people who resist these changes the most will shock you- Textbook publishers who have made millions selling the same teaching methods every year between new covers.
Teach this method to kids, and they pick it up like magnets. Once you free their minds and show them they can *enjoy* learning, nothing in the world but old ideas ever hold them back again. Imagine what a world that might be in 20 years time.
What useless shit to waste brain space on. I'm doing a masters in physics and have a bachelor in physics and mathematics and I can tell you that there is almost a negative correlation between how good people are in those fields and how good they are at multiplying and adding numbers in their head. Knowing tables are a complete waste of headspace. It is not going to make life easier for anyone in this modern world and it is pretty much non-constructive for learning real mathematics.
Calculators became publicly available in the 1970's. So you are saying you were alive *before* 1930?
@@pawthorne7089 Not just alive, apparently, but old enough to be studying difficult enough maths that a calculator might be used for it today (in UK education that would probably mean 11+. but Roci may well be from somewhere else in the world).
The abacus is over a thousand years old.
An old man showed me a different way to do division. He thought the teacher would be impressed. She told him I was" just confusing the child" .They must learn to do it as the department of education requires and it was also required to write everything on paper as otherwise I was just guessing at the answers. Memorize everything, write it on paper , prove that you did it their way and no oral testing or doing it in your head. That was 1st grade, by 3rd grade they tried to teach us algebra as an experiment and it was a failure. Real and non real numbers? To a 8year old?non real is imaginary and could not be written down on paper. Who was Confusing? Algebra came in the 8th grade and nearly noone could do it. Thanks to the Department of Education ,State of New York 1960-70's They were stupid.
This guy is the human calculator but man is he taking his time explaining this

We've got someone in my village who does Arithmetical operations, be it plus, minus, multiplication or division instantly. Most surprisingly, the person was a drop our in secondary school. More so, he tells number of days, hour, minutes and seconds given any date and does it precisely. He tells dates when number of days from a particular date is given to him. The man was tagged human computer. He lived in a town Zaria in northern Nigeria. The man lived in the early 90s and I do not know where he is at the moment.
He sent me an email last week saying he'll give me $9 million if I can help him get out of the country.
maybe someone can find him and make a youtube video
he actually said "can you repeat that in human" im tripping
I learnt to calculate in certain ways. I learnt to calculate in more ways with years and experience.
Some things are taught with time, effort, luck or if "you have it in you"; at school they teach us mostly the basics, things that have a solid base. It's up to the teachers to show us how to think smarter and quicker, but even then not everyone likes the same things.
Everyone saying he is showing off I guarantee are the same people who take pics on social medial of every new thing they get. This dude found his own way to learn to me that’s worth showing off.
I like how the whole angles-in-numbers thing was some irrelevant, ad-hoc sophistry that didn't even work right and had to actually alter some of the numbers drastically.
That's not accurate. Numbers are not written the same today as in the past. In the past you could count the angles to know what it represented, as he showed.
Gary Sutherland we actually just adopted arabic numbers and some changed some didnt, no angles involved
@@garysutherland7004 No, the angle story is completely bogus, no evidence for it whatsoever.

Mind was blown away how easy it was just to sit here and learn maths,
When he's going on about where the symbols for those numbers came from, this is fairly well known knowledge, not sure why it took him 30 years to find it. Additionally, half the stuff he's saying only works in ENglish and it pure happenstance. The rest is just mnemonic devices that will work for some but not for others.

I’m still trying to figure out why we start the year on January 1st. Wtf
In Britain and the colonies, until 1752 the New Year was March 25. Good Protestant nations couldn't use a Catholic calendar, now could they?
Janus is the Roman god of beginnings, transitions, time. Since Julius Caesar made the Julian calendar he thought it would be appropriate to make the first day of the new year on the first day of the month of Janus (January). The original 1st day of the the new year was April 1st. When new years day was changed to January, people would still say happy new year on April first, and people would call them April fools for forgetting it was changed to January.
*January 0th*

I came here after Nas daily. Thanks scott.
OMG! SAME!
the math have never interested me. I was happy to have understood the basics of algebra. But strangely, I was the best in geometry and I was able to memorize the calculation tables entirely (without really to understanding them). In the early 80's when the first computers like the SINCLAIR ZX 81, COMMODORE C-64 and AMSTRAD were available, I started learning BASIC and MS-DOS - but only because I was able to memorize everything the programming schemes and conclude the logical sequence. So I became a cartographer for the mapping of sattelite images in the military. But even today I do not understand maths in context - but only if I associate these equations with an image or an object in the form of variables ... I believe the brain of each one of us works differently but we get everything (more at least) to the same result ;-)
maybe so
I'm just stupid and lazy when it comes to math. My brain immediately goes into hibernation
29:00 I wonder if anyone adds like me: I add from right to left, but I look in the right column for numbers that add up to 10, by scanning. So in 1st example he used, 7, 2, 1 instantly popped up in my head as a 10, so I don't add those, I add the remainder to it, then add the total with the total on the next column, which same rule can be applied. If you have for example 2, 2, 2, 2, 2 or 6, 2, 2 , that's an instant 100, I don't add them but whatever is left in the column gets added to it. Also works by scanning which rows can be combined to make multiple of 5, and you count how many times the pattern appeared, then you add whatever rows couldn't fit to the pattern. I'm nowhere near capability of this guy, but I can add in my head faster than a "normal" person.
2nd case - was very slowly delivered, 6, 3, 1 instantly recognized as a 10, added 8, then added digits in 2nd column - 70 plus 18.
In a nutshell, is recognizing the patterns of numbers that create a fixed amount (usually 10) and add how many times that pattern repeats itself.
Hope this is not very confusing, I'm really curious if anyone else uses this method.
Finally!! I thought I was some kind of freak for doing that too.
I do that too, well.. not anymore because im trying to get the method in the video into my brain lol
I think this Method of adding from left to right works in the English language but at least in Germany to say like 54 we say vier=4 und fünfzig=50 so its easier to add up the right diget first
This is great! I have always look at math a different way. In 4th grade I found my own way to multiply by 9s

I Like Flansburg, and I have Improved my math skills by learning his techniques. But I disagree with thinking of the first finger as 0. Sure we should count from 0, I don't dispute that, but we should start with no fingers up as 0, not the first finger. We should make sure that 0 is not being translated as 1, but as the point before you start counting, or adding in anything.
Think of an infinite line and what breaks it up into units that we can use, e.g. to measure the distance from your house to my house or from my planet to your house. We have to pick a more-or-less arbitrary starting point, which we call zero, and we have to define a unit of length, say a meter, and lay it out on that line with one end at zero. Then the end of the first meter is 1. In between are fractional values of that first number, which we need to be able to deal with. So in one way it is very natural to start with zero. What we were doing with 0-9 and with 1-10 was not made clear to me in elementary school, and I still get confused and have to draw a picture or two to get myself clear on things. It would have been more natural if in school we would have started with measuring distances, specifying that we start having gone zero miles, then when we have gone a mile we put down a roadside marker saying, "One mile form home," and so forth. We could do the same thing, filling a measuring pitcher up with a third of a cup of water, adding more water to make a half cup of water, and so on. Starting with one little lamb, two little lambs seems natural, and indeed that is probably the way numbers were first used. If you were a sheep herder you hoped you had only whole lambs at the end of the day, and you didn't count a zeroeth lamb returning to the fold, but on the whole, starting out this way can lay down landmines for the future.
The day-calculation trick that he mentioned looks like
["Sun","Mon","Tue","Wed","Thu","Fri","Sat"][((Y+(Y/4|0)+D+[0,3,3,4,1,4,6,2,5,0,3,5][M-1])/7|0)%7]
in JavaScript. Which is kind of interesting because every web browser understands JavaScript even if it isn't connected to the web... just create a New Tab, press F12, click Console, then input a date like
Y=2001; M=9; D=11;
Press Enter, and paste in the algorithm, and press Enter again, and it'll tell you the day of the week, which in this case is Tuesday. It's not quite correct, though, because it doesn't work correctly before 1900 or after 2100 because those years are normal years, not leap years.

He is very skilled, but is not being fully forthcoming in how he achieves some of his results and is not as informed as he pretends to be.
The cube root trick he does early in the show is a memorization trick, not a calculation and can be learned by anyone with a decent memory in half an hour. The limitations are that the cube root must be a 2 digit integer and the number he is given from which to "calculate" the results must be a perfect cube. You can find a youtube video showing how to perform this trick if you are interested--I think tecmath has one. You will need to memorize the cubes of the numbers from 1 to 9 and that plus a very simple 2 step method is all you need. No calculation at all.
In addition, the story about how the numbers got their shapes is apocryphal. The original shapes looked absolutely nothing like the shapes he drew.
I realised he must be memorising the cubes, as he didn't even listen to the whole number before answering so couldn't be performing a calculation on it.

37 x 10 = 370 + (37 x 1) = 407
3 goes in the hundreds column and 7 goes in the ones column, giving you 3_7: since 3+7 gives a two-digit answer, regular addition applies to the hundreds column and thereby increases by one hundredth or 4 placed in the hundredths column. That zero tens and four hundreds. Hence, the answer is 407 (instead of being stuck with 3+10+7 or erroneously arriving at an impasse of 3107).
